Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Would it be bad if I let my air conditionning unit (window mount unit) running during the winter? I live in Canada,Quebec and -20C is pretty common even -30C
Just turn on the fan, no reason to run the AC unless you wanna remove moisture from the air. Oh and you are insane, I like cold air for my comp as much as anyone but I couldn't stand my room being that cold, heh. But yes, it would improve your temps of course, the cooler the ambient are the cooler all your temps will be.
